PERFORMANCE EVALUATION OF THE IRD RSUP DR. SARDJITO BUILDING TO THE INFLUENCE OF EARTHQUAKE

Abstract: In performance-based
design, the level of performance of hospital buildings is generally
operational, where the buildings are expected to continue to function after the
occurrence of the earthquake and do not undergo significant damage. This
research evaluates the level of performance suitability of the Emergency Care
Installation Buildings of Dr. Sardjito Hospital (hereinafter referred to as IRD
RSUP Dr. Sardjito building) for the effects of earthquakes. First evaluation is
done by Rapid Visual Screening by FEMA 154 (2002), then continued with more
detailed evaluation based on FEMA 310 (1998). The building structure is modeled
by SAP2000 and created in 2 models, i.e. the Models with wall and the Models
without wall. The earthquake loads refers to SNI 1726-2002. The strength of
structural elements is calculated with SNI 2847-2002 and Response-2000. For
evaluation of structure performance levels, a pushover analysis used for
nonlinear procedures, where the analysis used to the Seismicity region 3 and 4.
Performance point is determined by Capacity Spectrum Method based on ATC-40
(1996), which has built-in in the SAP2000 Program. The performance level of the
building is determined by drift ratio criteria required by FEMA 356 (2000) as
well as ATC-40 (1996). From the research results, it is obtained that the
natural period for the Model with wall is 0.592 seconds and 1.687 Hz frequency,
and natural period for Model without wall is 1.291 seconds and 0.774 Hz
frequency. Therefore, the level of structure performances for earthquake return
period of 500 years is immediate occupancy.
